You can picture the cover now...
Scene - The Ro-Jaws Home for Retired Comic Sidekicks.
The Gronk sits reading a Black Flame Stronty novel.
Grobbledonk and and Walter the Wobot are playing Go Fish.
Ukko is sat under a tartan blanket watching Monarch of the Glen on the telly.
A nurse is shown bursting through the door with the speech bubble -
"It's Tharg on the phone...and he wants you back!"
Though it has always been alluded to. Slaine meeting up with Ukko has never been covered.
As I had seen a majority of Slaine Progs & graphic novels out of sequence before I ever got to read the first one online 'The Time-Monster' http://www.2000adonline.com/?zone=thrill&page=thrillviewer&choice=time
Then seeing that it shows that both had already been traveeling around Tir-Na-Ogg together.
That's unless I missed it!
Of course, that unless it's probably better off that way.
Does the R-JHome4RCS have a picture of Wulf above the fireplace, in honour of one of the few fallen 2000AD sidekicks?

And it's Grobbendonk - slarty var!
Would Helm, Gunnar & Bag Man count as sidekicks as well.
Heh, I'd love to see that, a hat, a backpack and a gun as residents in a retirement home!
Gunnar and Bagman are playing chess, Bagman with his dispenser-arm, and Gunnar with his telekinetic powers.
Gunnar: "Fancy a game, Helm?"
Helm: "Oh, very witty, I'm sure."
Bagman "I'd come over here and headbutt him for that one, Helm."
Helm "Yes, ho ho - very good."
etc.
Who's the little Skeletal being from Moonrunners.
It would be Ace Garp's little buddy.
You mean Feek the Freek from Ace Trucking Co.
Yeah, but I would be flat out finding a picture.
I don't suppose there would be any character in 'Bad Company' that would suffice also.
Perhaps Dogman or the plant creature.
Rereading your post, I made a bit of a mistake, whoops.
It's just that, I don't read a awful lot of Trucking Co & Moonrunners. I might mistake one for the other.
Now I remeber there was Woman & something that looked abit like Ukko, but not.
There's also Quinch.
