Japanese has exactly two irregular verbs, する and 来る, and they have a group to themselves. The する group below holds the compounds — 勉強する, 電話する — which are する with a noun in front and conjugate exactly like it.
来る (kuru) is one of only two truly irregular verbs in Japanese (along with する). Unlike godan or ichidan verbs, its stem changes unpredictably across conjugations:
Notice how the reading changes: ku-ru → ki-masu → ki-te → ko-nai. This vowel shift (u → i → i → o) doesn't follow any standard pattern, which is why it must be memorized separately.
Every verb above is one the Conjugator can drill — forwards, or backwards in Rewind.
