Perking a little as he heard the greeting from a certain dragon boy, the blonde boy managed to see a charging Iggy. Which initiated both excitement, happiness, and panick. Karn, in comparison to Iggy, was much more fragile in his human form. Iggy could probably break a few bones with a simple hug. But, Karn always liked hugs from his friends, so quickly the blonde's body transformed into his Chimera. The beast able to take quite a lot, even said to get back up from a dragon's attack.
So as he was tackle hugged, he laughed and wagged the long tail happily.
"Hey Dragon boy! Missed you!" Karn chirped happily, chuckling at Mimi called her longtime friend a Baka before addressing Luka.
"Hi Lightning!" he chirped, seeming not to notice her maybe bad mood as she started yelling before looking to another guy who came in.
"Hello!" Karn cheered, feeling to need to say just about hello to everyone he sees. It's been a long time since he had been home after all.
Ears perking as he heard some noise outside, Karn simply happily called out. "Hi person who decided to ride with me!" he laughed before he playfully put a large paw ontop of the fellow blonde boy's head and ruffled the short hair.
"Hope you guys have been alright while I've been gone!"
