Okay, here we go! Last three English and original.
So let me break this down:
#4 from Sept. 95 is the first to call anything in-comic "Timebuster," and it isn't the kid - it's the time machine.
The next one, from November, goes back to just calling the time machine "the time machine" and decides that the kid's name is Max Timebuster.
#6, the first 96 issue, conspicuously calls the kid just "Timebuster" repeatedly, leaving out "Max"
#7. The kid's shirt is changed from purple with an L to green with a T without explanation. The time machine becomes the Time Cruiser. Because this happens, he decides he needs to give himself a name that starts with a T. This apparently has nothing to with the new T on his shirt or anything else
so uh. thats. thats how he went from max to tim.
There are a couple of things still missing from the picture between here and the beginning of the World Club stuff: Ali/Ingo the monkey needs to be introduced somehow, and it sure would be nice if Tim could stop by the professor and at least let him know that he, like, didn't die or anything (it totally isn't going to happen though). The way these Klick ones are running is 8 pages per theme, and there should be about 20 pages (give or take) of the comic that we're missing. That leaves room for the 6 more Exploriens (and Spyrius?) pages, an 8-page Wild West arc, and ~6 pages for the Time Twisters.
Merry Christmas! One more year of me finding more of this stuff around this time and it'll become a holiday tradition.
