What toy lines did you have/collect as a child?

Wow, that’s pretty awesome! I never got much from my extended family. I also never completed any Transformer sets! I just arm and leg pieces!

I went through a few obsessive phases until I got stranded in the most embarrassing obsession of them all: wrestling

Living in the UK I guess we didn't have great access to US toys, but they were my focus so I got what I could. IIRC it sort of went like this, starting in the mid-to-late 80s:

-Transformers: only had a couple of these I think, mostly remember an awesome Optimus Prime
-Ghostbusters: first real obsession; I had the four main characters, Ecto-1, the fire station, the yellow beetle, Slimer, Stay Puft Marshmallow Man, and a few other random characters
-Batman: short-lived obsession this one, but had Batman, Robin, Joker, the Penguin and a few others, as well as the Batmobile, the Batwing and the Batcave (with the prison on the other side)
-Teenage Mutant Hero Turtles: had I lot of these, my favourite probably being this vehicle that fired pizzas at evildoers

...and finally started watching the WWF starting with This Tuesday in Texas in 1991.

From there the Hasbros were (and still are) my obsession. I had two Galoob figures at the same time (Tom Zenk and Ron Simmons) but I didn't know who they were, just that they were wrestlers I could use as jobbers for my Hasbros. The Galoob ring was the first ring I had, before I got the Hasbro one with the soundbox, so I used the WCW one for cage matches. I never saw any LJN figures, but if I had then I'd still probably not been interested as the Hasbros were dominate in my world.

I tried and tried to get as many Hasbros as I could but as the line went on they were declining and fewer stores were carrying them - I probably had the second biggest collection behind this one rich kid friend of mine who had everything imaginable, and most annoyingly of all he was a really nice and fun guy so I couldn't even hate him. I then began collecting the Hasbros MOC in late 1997 once I discovered eBay.

I never liked the Jakks figures, but when stores started carrying them here in 1999 then I bought a lot of them to keep MOC, because obviously the Jakks figures would increase in value in the exact same way the Hasbros had already done at that time... It was also easier to buy Jakks in stores then it was to buy Hasbros from eBay (though I did buy plenty of them as well), so now I have boxes of Jakks and WCW Toybiz figures that aren't worth what I paid for them back then, while the Hasbros are still increasing in value seemingly everyday. 

Teenage Mutant Ninja Turtles were the first figures I remember collectiong but then I moved onto what got me into loving action figures.

Toybiz X-Men and Spider-Man figures based on the animated shows from 90s. They were just amazing.

I’ve not even seen Robot Wars toys, do they have Panic Attack? I always liked that one.

Yes, honestly this was years ago. I remember the mini bots were like the Micro Aggression's where it was 3 per pack 

Monster jam die-cast trucks which I still have to this day.

Did any other 90s kids collect the monster wrestlers and ninjas that came with Kelloggs cereals? As I recall if you collected so many tokens and sent in 50p, you'd get a special edition figure.

There was even a Tony the Tiger referee / physio / trainer or some gimmick

Hmm........I don’t really remember these specifically, althought the blue guy and the jester seem vaguely familiar.

Only time I ever sent off for something from cereal was to get some aeroplanes and a model airfield from Kelloggs.
