1. Can you use super strength and mind control

2. Can you use super strength and close combat expert

sorry for asking i have been judging my place for a few month but we only play 1 to twice a month these where question ask me last week wanted to know if i rule right

Yes to both, but it probably not what you thinking about:

SUPER STRENGTH KNOCKBACK during close attacks. This character can pick up (and hold) heavy objects.

Those are two things Superstrenght allows you to do. You CLOSE attacks will cause knockback and you can carry and hold heavy objects.

Attacking with object (heavy or light) requires something else:

CLOSE Object Action: CLOSE: If this character is holding an object, make a close attack and modify damage +1 if the object is light or +2 if the object is heavy. Immediately after the attack resolves, KO the object.

RANGE Object Action: RANGE: Minimum range value 6. If this character is holding an object, make a range attack targeting a single character that, instead of normal damage, deals 2 damage if the object is light or 3 damage if the object is heavy. Immediately after the attack resolves, KO the object

Now Mind Control:
MIND CONTROL CLOSE/RANGE: Minimum range value 4. Make a close/range attack. Instead of normal damage, a hit character halves speed and becomes friendly to your force and may in either order: Move and/or make an attack. Then it reverts forces

During Mind Control you make an attack. You using your CLOSE/RANGE to activate MC, so you can give the character CLOSE/RANGE to use an object.

MC triggers an effect rather then deal normal damage, so the character won't be knocked back.

So technically you will be able to use Super Strenght but it will not so anything.

CLOSE COMBAT EXPERT POWER: Choose one: Modify attack +2, damage +2, or both +1. Make a close attack

Again you make CLOSE attack during after activating CCE, so you can;t give the character a CLOSE action to use an object.
You are however dealing damage during a CLOSE attack so the target will be knocked back.

TLDR;
You can't attack with object using either of these powers.
You can knockback targets however since MC doesn't deal damage the traget won't be knocked back.

If what you mean is, can you make an attack with an object during mind control or close combat expert, the answer to both is no.

However, super strength also gives KNOCKBACK which could be helpful during a mind controlled attack or during a close combat expert attack.

You could also use super strength to pick up a heavy object during the movement portion of mind control. You might have an stealth opponent hiding on a heavy object, you mind control their adjacent buddy who picks up the heavy object and walks away.

Oh yeah an MCed character can't use an Object while making an attack since CLOSE Object action requires a CLOSE action and they'tr juts making an attack, but they will cause knockback and will be able to pick up (or drop) Objects.

thanks guy sorry i should have put example of what I meant so nobody had to guess

Mind controlled characters can only move half their speed and/or make an attack, in any order. They can't activate any type of action, but they can use any passive effect from a power they have. If the mind controlled character has Super Strenght, they will cause Knockback should they make a close attack, or use Precision Strike as well.

I actually made a post showing the powers you can use during Mind Control, and it's a much more extensive list than I thought.

Nice!
