Hemi Jack is straight up the worst, most useless super in any version of Xrd, and I love it so much because of that. It is such a useless sheep that ANYONE with the slightest amount of braincells and knowledge of bedman is going to question why you threw it out, and that's why I try to throw it out at least once per match.
Technically, Hemi Jack CAN stun the opponent, so there's that, but the
damage DOES scale, so you need to keep the combos short and simple, and
that's about the end of the strategic benefits to Hemi Jack.
The downsides? Oh, where do I begin. You can hit Hemi Jack. If you hit
it three times, it goes away. If about 9 seconds pass, it goes away.
If Bedman gets hit, it goes away. Just putting it out puts bedman in a
VERY vunerable spot, too, so you have to be VERY sure
of what you're doing. In addition to this, you basically have to fling
your opponent into it in order for it to hit, since it doesn't hit grounded
opponents, and that's much, MUCH easier said than done with Bedman. In
addition to this, you can combo into instakill off of it, but good luck
because it leaves you far enough away that if you did stun, it's gonna
wear off before you can land an instakill.
Depite all of this, though, I can't bring myself to hate Hemi Jack. It's
such a little guy that I just can't help but love it. It's literally just
a spooky sheep! How could you hate it! It's also really satisfying to
actually get it to land. One of my main goals as a Bedman main is to one
day be able to combo off it into an instakill, and I've almost done it
once online!
