Ok, how about a 5kg titanium circular saw that can retract into the body?

How does it retract into the body? Electrics? Please state these kinds of things in your stats.

Intrigue vs. Nitro-Gene 4.0

Its kinda short, and you didnt state some stuff that you should have. For instance...

Intrigue comes in and presses the pit release button, as Nitro-Gene gets under him, and flips him

Where did Nitro-Gene get under Intrigue? How did Intrigue recover from the flip?

He succeeds, but not without getting flipped upside-down by Nitro-Genes flipper.

How can Nitro-Gene flip someone from the side? Flippers dont do that.

Intrigue now pushes Nitro-Gene onto the flame grill, and now into the angle grinder. Nitro-Gene is not moving, so our special guest refbot, The Watcher, will now count out Nitro-Gene.

How did Intrigue push Nitro-Gene? Did he get under and push, or did they cancel out, and Intrigue was more powerful? How did Nitro-Gene stop working? Also, you dont use other peoples refbots without permission.

Just a few things to consider.
