If an effect changes under whose control a token would be created, that effect applies before this creature’s effect applies. If an effect changes under whose control a token would enter the battlefield, that effect applies after this creature’s effect is able to be applied.

The additional Thopter token won’t have any abilities the other tokens were created with. Anything else specified in the effect creating the token (such as tapped, attacking, or “Exile that token at end of combat”) applies to both the original tokens and the Thopter. Similarly, if the effect that creates the token has an additional effect that gives the token an ability, such as “That token gains haste,” that effect will also apply to the Thopter.

If you copy a permanent spell, that copy becomes a token on the battlefield, but that’s not the same as creating a token. You won’t get an additional Thopter token that way.
