I just got a new Root Fossil and I was going to make it the be a Pokemon, So I emptied two slots in my party because that a another Pokemon was waiting. I don't know how but I received a perfectly legitimate Arceus. It could still battle. At first I thought it was just named Arceus, but when it came in my party I seen that it was real. It was Lv20 with regular Arceus moves.
I've heard it's possible to get legendaries via the oreburgh city mining museum, but never without the involvement of the AR or any other hacking device I know of. I've heard it's been used to get legends like cresselia and deoxys, but never arceus. maybe it could be a really rare glitch of some sort?
Interesting. Can you elaborate a bit on this? Like, what was the first fossil you gave to the scientist, anything surrounding that fossil that might have done it, anything that happened between the times you gave fossils, etc.? I want to do it/see it for myself. xD
These kinds of stories always remind me of the 'Celebi glitch' back in gen III.
Long story short- it was claimed that the programmers did a shoddy job on route 123, resulting in a floating piece of code being left hanging around. Normally it did nothing, but 1 in 268435456 battles on the route will encounter a Celebi. While most people were tempted to write it off as fake, like the infamous 'AFTER 100 ROCKET LAUNCHES IN SPACE CENTRE YOU GO TO MOON AND FIGHT DEOXYS' fake cheats, there was something tenacious about this rumour. I'm tempted to give it the benefit of the doubt- the few people I've talked to that claimed to have encountered the Celebi all seemed honest and credible, and it is entirely forseeable they're right. Here's the page if you're interested.
He called it Arceus. He said: "You kept us waiting!! Here is your ARCEUS. You take good care of it!"
