Neon Katt is a member of Team FNKI, of Atlas Academy. She participated in the Vytal Festival Tournament, fighting against Yang Xiao Long and Weiss Schnee during the doubles round in the episode "Never Miss a Beat". Neon has a ridiculously bubbly and hyperactive personality. She also seems to take great joy in provoking her opponents, immediately mockingly mimicking Yang's speech and attacking her for her weight and appearance. In battle, she retains this attitude, taunting her enemies and cracking puns that even Yang fails to appreciate. However, once beaten, she does respect her opponents, calling Yang and Weiss "super crazy awesome" and asking them to party sometime.
