How to get a super strong "permanent" level 255 Pokémon (Red/Blue)

Read description for more information:

In this video I obtain a hybrid of two glitch Pokémon (hex:E1 and hex:F1) with glitches that don't require linking. You can try others, but this was the best I could immediately think of. If you want to make your own, try merging a Pokémon with a fast experience group (as recipient; byte 2) with a Pokémon that seems to require a huge amount of experience at level 100.

Glitch Pokémon growth rates: forums.glitchcity.info/index.php?topic=6588.0

Hex:F1 will be species byte 2 (the "recipient") and hex:E1 will be species byte 1 (the "donor"). Experience is capped to byte 1, while the growth rate (a.k.a. experience type) is determined by byte 2.

For normal Pokémon the max experience should correspond to level 100, but it doesn't have to.

Hex:E1's cap seems to be a ridiculous amount of experience (16160812 or hex:F6982C if it doesn't vary), while Hex:F1 (aka 94) levels up relatively fast, with ~850,000 experience at level 100. You can level this Pokémon up to level 255 and have it not drop levels. The only way to revert it back to a lower level is to level the Pokémon up again with Rare Candies, or theoretically take it into the Day Care. Unfortunately the Pokémon we get will know Flash, meaning Day Care is not an option without using arbitrary code execution.

The base stats are taken from byte 2 (which is hex:F1). Hex:F1 has the following base stats. HP:142 ATK:142 DEF:139 SPD:147 Special:145. These base stats rival Mewtwo, though Mewtwo has 7 points better Special.

Walk through of what I'm doing:

Part 1: Getting 'M (FF) for Pokémon merge glitch:
--------------

Prepare a Ditto with the CoolTrainer move (swap 2nd-4th move with first after Transform). You need a 7 letter name, unfortunately. You'll also need a Pokémon with Fly or Teleport and access to Vermilion City.

To get the end "perma-255" Pokémon, you'll need at least 128 Rare Candies (theoretically you can do the Elite Four many times, but the experience at level 255 is extremely high). Prepare at least 3 Master Balls.

1) Do the Safari Zone exit (Glitch City) glitch. To do this, enter the Safari Zone, go out to the entrance and say no, save and reset, then go out and say no to activate the glitch (the game will think you're in the Safari Zone when you're not).
2) Land your last Safari Zone step in Route 1 and enter the Route 1 Glitch City by walking through the exit after you're warped to the Safari Zone entrance.
3) Open your menu here i.minus.com/jbia9KQ4whZJpb.png, and Fly/Teleport to Vermilion City. Make sure Ditto is in the first position before you Fly/Teleport away.
4) Enter Diglett's Cave then enter a battle. Don't open the start menu during this step.
5) Keep viewing the CoolTrainer move by scrolling on the moves list/opening closing the fight menu until its type changes.
6) Throw a Master Ball at the opponent to get 'M (FF)
7) Call it PkPk for part 2.
8) Open the menu and close it to avoid a freeze before exiting the cave.

Part 2: Getting hex:E1 and hex:F1
----------
9) Go east of Vermilion City and open your menu here. i.imgur.com/hXz9XXB.png
10) Enter a wild Pokémon battle and do the mutation glitch again (apparently depending on your exact name the glitch may only work without a freeze in Diglett's Cave, sometimes it won't).
11) Switch to "PkPk" (notice Pk is hex:E1) and then back to Ditto again.
12) Don't open any more menus, then do the mutation glitch again and throw a Master Ball to get hex:E1.
13) Call it xx (two multiplication signs), because x is hex:F1.
14) Repeat steps 9-12 but switch to "xx" instead. This will get you hex:F1.

Part 3: Merging hex:E1 and hex:F1
-----------

15) Switch to an empty box and deposit the following Pokémon (the order matters): 1) Ditto, 2) 'M (FF), 3) Hex:E1 (I called it "xx"), 4) Hex:F1
16) Withdraw Ditto, then withdraw the Pokémon two spaces below Cancel. You've now got a hex:E1, hex:F1 hybrid.

Part 4: Leveling up
------
17) Rare Candy it up to level 255 (the CoolTrainer gave the Pokémon over level 100). It will stay at level 255 even when you deposit/withdraw it or battle with it. To avoid a potential freeze from one of the Super Glitch moves it learns, Rare Candy in this spot in Celadon Mansion. i.imgur.com/LKSK8Nm.png

Downside: 94 learns Flash as a starting move. You won't be able to erase it without arbitrary code execution.
