Spike (Lab Rats)

Spike is the agressive alter-ego of Chase Davenport. He tends to solve everything with violence, though sometimes he's also seen arguing with the principle.

Personality
Spike is in many ways Chases opposite, while Chase is a nice if somewhat meek hero, Spike is an assertive, cruel, agressive but honest soldier. He is also selfish and violent and never afraid to knock others down if he feels they are in his way. He does share some traits with Chase however as both of them have leadership qualities and both are quite cocky.

Spike also shares all of Chases powers and martial arts skills, but unlike Chase he's got no problems exploiting them for his own selfish gain. Due to this and his aggressive tendancy's Spike is feared by Chase's siblings, and often panic when ever he emerges.
