Pokemon Uranium Best Pokemon: Top Picks, Tier List, and Team Guide

Pokemon Uranium flips team building on its head, and that is exactly why so many players struggle to name the Pokemon Uranium best pokemon. Because Nuclear-type attacks hit almost everything for super effective damage, the strongest picks are not the ones with the biggest base stats — they are the ones that survive a Nuclear hit, pivot out, and punish whatever your opponent leaves in. This guide ranks the top picks, explains the roles they fill, and shows you how to build a six-monster squad that clears gyms and the endgame alike.

If you want the short version: Nucleon, Metalynx, and S51-A carry most runs, while Dunseraph, Terlard, and Pajay round out the supporting cast. The longer version — including why each one works — is below.

What Makes a Pokemon Great in Pokemon Uranium

Uranium is a fan-made RPG built on a familiar engine, but its signature type changes everything. Nuclear attacks are super effective against nearly every type in the game, so defensive typing matters far more than raw power. Community testing suggests Nuclear moves hit single-typed targets for double damage and dual-typed targets for four times the damage, which is why fragile dual-typed sweepers melt the moment a Nuclear attacker switches in.

There are two reliable answers. The first is Steel: a Steel typing halves incoming Nuclear damage, which is why a Grass/Steel starter like Metalynx ends up neutral against Nuclear attacks instead of weak to them. The second is the Nuclear type itself — Nuclear resists Nuclear, so a Nuclear-type attacker can trade blows with the endgame's nastiest threats. The game itself has an unusual history worth knowing, and the Pokémon Uranium Wikipedia entry covers its fan-made origins and the takedown that followed its original release.

Nuclear matchups (community-tested)

The takeaway is simple: a team of dual-typed glass cannons is a liability. Every slot should either resist Nuclear damage, outspeed the threat, or hit hard enough to end the fight in a single turn. That is the lens through which the Pokemon Uranium best pokemon should be judged.

The Pokemon Uranium Best Pokemon: Six Community Favorites

These six show up again and again in community tier lists and team-building discussions. Some are gifted to you during the story, some require patience to raise, and one is widely considered the most broken pick in the entire game.

Nucleon — The Nuclear Sweeper

Nucleon is the closest thing Uranium has to a win button. It is a Nuclear-type evolution of Eevee, and its ability converts Normal-type moves into Nuclear-type moves, which means a single Hyper Voice suddenly hits almost the entire game for super effective damage. On top of that, Nucleon resists Nuclear attacks, so it can actually stay in against opposing Nuclear Pokemon instead of being forced out.

The trade-off is brutal: Nuclear-type Pokemon are weak to essentially every other type, so Nucleon dies to almost any neutral hit that connects. Play it as a hit-and-run attacker. Bring it in after a KO, fire off Hyper Voice, and switch out before your opponent gets a free turn.

Metalynx — The Starter That Never Falls Off

Metalynx, the Grass/Steel starter, is the definition of a safe pick. Its typing gives it a long list of resistances and a neutral matchup against Nuclear attacks, which is rare in a game where dual-typed Pokemon take quadruple damage. Community reports consistently note that it handles the majority of gyms without help, and its learnset is deep enough that it never feels like dead weight.

Metalynx can also Mega Evolve, which pushes it from a solid wall into a genuine offensive threat. A typical set runs Leaf Blade for Grass STAB, Iron Tail for Steel STAB, Earthquake for coverage, and a fourth slot for whatever your team is missing.

S51-A — The Endgame Answer

S51-A is handed to you during the story, arrives late, and is absolutely worth the wait. Its Steel/Psychic typing gives it the bulk to eat a hit from the final boss's strongest Pokemon while still dishing out meaningful special damage. Psychic and Flash Cannon are the core, with Energy Ball and Focus Blast filling the coverage gaps.

Think of S51-A as the anchor of your team. When Nucleon or Pajay goes down, S51-A is the Pokemon you switch into — not to sweep, but to stabilize the board and force your opponent to commit.

Dunseraph, Terlard, and Pajay

Dunseraph is the reward for raising a Dunsparce all the way to roughly level 42. Before that point it is genuinely painful to use, but the payoff is a bulky Dragon/Flying attacker with Dragon Pulse, Air Slash, Flamethrower, and Roost. Just keep it away from Nuclear attacks — as a dual-typed Pokemon, it takes four times the damage.

Terlard is the opposite experience: a Ground/Dragon physical attacker that comes online early and stays useful. Earthquake, Dragon Rush, Stone Edge, and Iron Tail give it enough coverage to break through most mid-game walls.

Pajay rounds things out as a Fire/Flying special attacker with Flamethrower, Air Slash, Will-O-Wisp, and U-turn. It handles the Steel-types that otherwise wall your Nucleon, and U-turn lets it chip damage while keeping momentum. Just avoid anything faster than it — Pajay's bulk is not its selling point.

How to Build a Balanced Team

Six strong Pokemon do not automatically make a strong team. Uranium punishes redundancy, so assign each slot a job before you start grinding.

A few practical rules that experienced players repeat constantly:

• Never stack Nuclear weaknesses. Two dual-typed Pokemon that both take 4x from Nuclear will cost you runs.
• Keep one Steel-type alive at all times. Steel's Nuclear resistance is the cheapest defensive tool in the game.
• Build for the next gym, not the last one. Uranium's gym leaders punish single-type teams hard.
• Train a sixth Pokemon even if you rarely use it. The endgame boss punishes a five-monster squad.

Movesets That Work

Community Tier List Snapshot

TierMaker hosts a community-built Uranium tier list that aggregates votes from dozens of submitted rankings, and the results shift as players discover new strategies and patches adjust movepools. Based on those community rankings and the team-building discussion above, here is a practical snapshot of the Pokemon Uranium best pokemon tiers.

Treat tier lists as a starting point, not gospel. A B-tier Pokemon that covers your team's specific weakness is worth more than an S-tier pick that duplicates a role you already have.

FAQ

What is the single best Pokemon in Pokemon Uranium?

Most players point to Nucleon. Its ability turns Normal moves into Nuclear moves, which hit nearly everything for super effective damage, and it resists Nuclear in return. That combination trivializes large portions of the main story. The catch is its frailty — it dies to almost any neutral hit, so it needs careful switching.

Do I need a Nuclear-type to finish the game?

No, but it helps enormously. Steel-types like Metalynx and S51-A resist Nuclear damage, which gives you a defensive path through the late game. A Nuclear attacker simply makes those fights faster and less punishing.

How many Pokemon should I train in Pokemon Uranium?

Six, and rotate the sixth slot based on the next gym. Uranium's leaders punish teams that lean too hard on one type, so keeping a flexible counter ready is more valuable than over-leveling a single ace.

Is Dunsparce worth the wait?

Yes, if you have the patience. Dunsparce is genuinely rough to use before it evolves, but Dunseraph's stats and movepool make it a legitimate late-game threat. Just remember it takes quadruple damage from Nuclear attacks, so keep it away from Nuclear sweepers.

The Pokemon Uranium best pokemon list ultimately comes down to roles, not raw power. Lock in a Nuclear-resistant wall, add a Nuclear sweeper, cover your physical and special damage, and keep one flexible slot for whatever the next gym throws at you. Do that and the endgame stops feeling impossible.
