Mitsuki's signature technique is the Soft Physique Modification technique, where he can stretch and lengthen his arms to use as weapons and restraints.

Is seeing carrying sword suggesting he is trained in kenjutsu.
Mitsuki can use many techniques in conjunction with his snakes such as Snake Clone Technique and Hidden Shadow Snake Hands.

Two notes:
1. There is also a possibility of a connection between embryo used to make Mitsuki and Toneri Ōtsutsuki.
2. Orochimaru noted he is potentially even more powerful than the Sannin himself.

So how strong do you think Mitsuki is? And how strong will he be at the end of the series?
Also check and discuss how strong are Boruto and Konohamaru.
