I can't say I've ever had Pokemon inspire me for a game, but it did inspire a motivator that I have yet to make. If anyone knows where to find an online version of the Gingerbread Man picture book, please tell me.
Returning to the idea of Pokemon, Pikachu can likely be replicated to some degree of accuracy using Soulmelds. I'm fairly certain there was one that gave claws with lightning damage or something and another entirely that fired an actual targeted lightning attack. I could be wrong on both counts though. If I'm right, you could make an Awakened Rat with the Shape Soulmeld feat.
Lightning Gauntlets and massive amounts of Bloodline abuse. But the Lightning Gauntlets do not give the Claws or Tail. Wormtail Belt bound to Totem, Rage Claws bound to second Totem, Shape Soulmeld for Lightning Gauntlets, Dwarf followed by PaO to get qualifications and the body. Then it is:
Totemist 4/Barbarian 1/Warblade 1/Totem Rager 5/Ironsoul Forgemaster 4/Legacy Champion 2/Major Bloodline 3
Meldshaper Level: 26
Essentia Capacity as a 35th level character.
Nice number of Chakra binds (crappy slot selection though).
Elder Mountain Hammer for Iron Tail.
Lightning Gauntlets for Thundershock.
Rage Claws for near-immortality.
etc.
The only serious problem is the low Essentia. Most of it will be in whatever you are using that round. The rest should be in the melds you want to have bound.
