It should be noted that Mettaton upscales over his AP value
(Mettaton SPIRAL has an immense attack value of 70, thus stronger than
Undyne's and
Mad Mew Mew's 50 ATK, who are both already above
the previous timeline's Mettaton's 47 ATK.
47 ATK is 0.04476 Tons) and is far more durable than his AP (Undyne builts her robots with durability in mind, and MTT isn't an exception. This is demonstrated by him being
completely unaffected by any of Frisk's attacks during his playable fight. Mad Mew Mew, who should be around as durable as him,
no-sells an attack ("betrayal kill") Frisk that exploits her weakness which lets a far weaker Frisk
one-shot Toriel, who has a defense value of
80 like Asgore, who's so superior to characters like previous timeline Undyne (
50 ATK) to the point where
she considers herself killing Frisk to be mercy compared to what Asgore could do)
TL;DR:
Mettaton SPIRAL's durability >>>
Frisk exploiting Monster Weakness >>>
Asgore/Toriel >
Mettaton SPIRAL >
Undyne/Mad MewMew >
Mettaton EX
(>>> being one-shots and no-sells)
As for how he fights, Mettaton starts by;
- Creating numerous copies of his sword and sending them at his opponent before MTT throws his blade like a boomerang towards his opponent with high precision
- Throwing boxes at the arena to make it harder for his opponent to maneuver
- Raining bombs and blocks down on his opponent
- Summoning tiny copies of himself which will attack his opponent with deadly heart projectiles that home in on the enemy
- Create numerous drills that quickly emerge from all sides
- Creating enormous bursts of dozens upon dozens of electric bolts which are immensely difficult to dodge

He also of course combines all these moves with one another later on in the fight for more complex attacks
Other than that, Mettaton also
has a bunch of other miscellaneous powers. MTT can obviously
utilize his wings to fly around and keep his distance from Sonic.exe, MTT is
capable of slicing the bullet board and make it harder for his opponent to maneuver,
can record his attacks and rewind them to catch Sonic.exe off-guard,
capable of erasing the enemy's energy constructs with a blade slash, and due to still being a ghost, Sonic.exe will either need to completely destroy his body to truly incap him or actively attack his spirit to actually take him out.
