I feel bad for this dude, he and gatomon where myotismon's minions, but while gatomon was able to find a kid that gave a shit about her and save her, demidevimon got no one and kept his shitty ways, if gatomon wouldn't had joined Kari, she would had got eaten by venommyotismon just like this lil dude, who got mistreated by his master until the very end
