Accelgor

In bogs and marshy areas, where the humidity keeps its body from drying out, lives a light and speedy creature that has lost the shell from its previous stage. The blue membranes covering its body overlap to retain water, while the extensions on its back resemble bandages or a combat cloak. Its appearance combines traits of a slug or snail with those of a ninja, and its head, curved at the back, looks like an open helmet.

Pokédex entries describe it spitting poison and moving at breakneck speed. They also explain that abandoning its shell made it more agile, although the loss gives it a grumpy expression and folded arms. This combination of speed, membranes and acrobatic movements defines its behaviour both in battle and outside it.

It occupies the final position in a two-species evolutionary line. Shelmet evolves into Accelgor through a special trade with Karrablast, which also changes form during the process.

In battle, Accelgor is frail and highly specialised. Its HP is 80, Attack 70, Defense 40, Special Attack 100, Special Defense 60 and Speed 145. That spread makes its role clear: attack from the special side, move before almost any opponent and leave the field before taking a serious hit. Defense 40 and Special Defense 60 mean it does not withstand neutral attacks well, even with 80 HP.

Its hidden ability, Unburden, doubles its Speed when it uses or loses its held item. In singles, it can be paired with a consumable item to gain even more of a speed advantage, but this requires carefully timing its entry. Sticky Hold offers more consistent utility by preventing another Pokémon from stealing its item. Hydration only stands out in rain, where it cures status conditions.

The Bug type gives it super-effective attacks against Grass, Psychic and Dark, but its Bug-type moves are resisted by Fire, Flying, Rock, Steel and other Bug types. Defensively, it resists Fighting, Grass and Ground, while Fire, Flying and Rock hit it super effectively.

Spikes lets it punish switches, while Bug Buzz makes use of its 100 Special Attack with a powerful Bug-type move. Giga Drain covers Water-, Ground- and Rock-type opponents and also restores HP. U-turn lets it deal damage while maintaining the team’s momentum.

It is not a general-purpose competitive choice. Its place is on offensive teams that want to set up Spikes early or take advantage of its 145 Speed as a late-game cleaner. The opponent’s hazards, priority moves, Choice Scarf users and Fire- or Flying-type Pokémon stop it easily; switching directly into a powerful attack usually ends badly.

It belongs to the Bug Egg Group and has an even gender ratio: 50% are female. Its eggs need 15 cycles to hatch, equivalent to approximately 4080 steps using the usual formula. It does not receive egg moves, so breeding focuses on nature, abilities and individual values.

Its evolution requires a specific condition: you have to trade a Shelmet for a [Karrablast]. The trade causes Shelmet to evolve into Accelgor and Karrablast to evolve at the same time. Trading it for any other species is not enough.

It is associated with damp environments, such as marshes and bogs, because dryness weakens its body. Its catch rate is 75, an intermediate figure: it is not trivial to catch, but it does not require extreme preparation either. When breeding, the Bug Egg Group lets you pair it with compatible species from that group and obtain new eggs normally.
