Much like Jump Spark [link]
which was an electric type Scizor which had been injected with many things and experiment on by Team Rocket's RSquared Lab from egg form, This Pokemon from the second batch of experimentation and also became electric type. The earlier batch from which Jump Spark birthed could only become electric typed if they had originally been Metal typed Pokemon, However this batch used the data from the previous one to perfect the process, meaning other types such as water could be changed into electric type.
Totodile, Croconaw and Feraligatr all lost their water type traits however they still retain the ability to swim and surf while also having electric abilities.
requested that I make a alternate version of Totodile so here it is. I hope you enjoy it!
I drew this picture halfway through 2012 but only got around to editing it in Photoshop Cs3 this year (2013)
