Here's some info on hotspot I found:

Name: Hotspot ( His real name is Joto, to be exact)

Eye color: brown, when he's not on fire (lol?)

Hair color: brown

He's a human flame-thrower with a fiery temper to match! Hotspot met the Titans when the evil Master of Games held his own Tournament of Heroes super-competition. The contest was actually a ruse - the Master of Games was out to steal their super-abilities to use for his own evil purposes. The boy heroes joined together to defeat the Master of Games.

After this adventure, Hotspot was given a Titans communicator and made an honorary member of the team. Later, the Brotherhood of Evil hunted down teen heroes around the globe. Hotspot encounted Madame Rouge in Morocco and was one of the first heroes to fall. Hotspot was later liberated by Beast Boy's team of Titans. The combined might of Titans together led to the downfall of the Brotherhood.
