Biology

Slowpoke has fished up a Shellder with its tail, which shocked it into evolving and made it stand on two legs. The Shellder has transformed into a spiral-shaped shell to suck more sweet fluids from the Slowbro's tail. If the Shellder were to detach itself from Slowbro in any way, it would devolve back to Slowpoke.

Being slow-witted to begin with, the Slowbro does not feel pain in its tail because of Shellder's seeping poison. Since its tail has been bitten by Shellder, it has to grudgingly swim for prey instead. Whenever Shellder bites harder on its tail, it gives Slowbro a flash of inspiration, which it forgets a moment later.

Forms

Mega Slowbro

The original form of Slowbro consisted of a Shellder latched onto a Slowpoke's tail. With Shellder now taking up the majority of Slowpoke's body, it is apparently under Shellder's digestive fluid and it acts like a comfortable iron defense for it.
