Sonic's Battle Buddy
ソニックのケンカ友達
Sonic's Battle Buddy is a Battle Cats stage in Sky Sanctuary. It costs 150 energy and sends 7 enemy spawn lines — led by Knuckles (Enemy) as the boss — against a 120,000 HP enemy base, and clearing it rewards 235,000 XP. Its enemies carry the Red and Metal traits, so cats that target them do the most work here.
