My personal improvements of eeveelution learnsets, including a hypothetical wind element based final evolution.
Legendary groups
(Attempt to prove the mess of legendary groups can be organised properly. wip.)
Most legendary Pokémon are part of a group.
There are groups in which members share an equal amount of similarities (no member sticks out or has exclusive features, unless they all do with the same impact **) and there is the role of a master or guardian, who are related to a group but are superior to them in several ways.
Groups share a combination of many of the following traits ("+"-always the case):
- +specific method of encounter*
- +released in same generation
- +next to each other in pokedex order*
- +same stat total
- +secondary type, if any
- +similar learnsets (same levels, shared minor moves, comparable moves, especially STAB)
- +shared mythological background or origin story, if any
- -most cases even having exact same individual stat numbers in varying order
- -similarly working ability
- -similar design basis
- -main type
Masters might share several of the above traits with their group, but always have some clearly superior traits or exclusive features. Some masters might be part of a group of their own league.
- *There can be a few deviations in the case of version mascots (because of later releases of the third version) such as small dex-gaps and the final appearance being kept secret.
- **An exception is Suicune, who starred as the version mascot of Crystal due to lack of fitting candidates.
Legendary Trios
Most famous kind of legendary group, with 3 equally similar and equally contrasting members. These are the first legendaries to appear in each generation and have 580 total base stats
Generation IV was the "ultimate" generation, hence why instead of the usual trio, the version mascots themselves were a proper trio, meeting most requirements and of course having 680 total stats instead of just 580. These were accompanied by a sub-trio of all Psychic-type legendaries relevant to their plot, with matching colours. The traits of each Lake guardian (what they represent/method of obtaining/distribution of stats) seem to be based on the trios of the preceeding three generations (Birds - Azelf, Beasts - Mesprit, Golems - Uxie)
Giratina underwent a change with the release of its Platinum version, gaining a forme with altered stats, look, and ability.

 Kyogre Water |
 Groudon Ground |
| Weather duo | |
 Reshiram Dragon Fire |
 Zekrom Dragon Electric |
| Energy duo | |
There also exist imbalanced duos, each consisting of a parent and a child.
The first represents creation of life through artificial means (cloning), with the result being a stronger creature.
while the second represents creation of life through natural means (breeding), with the result being a weaker version of the original.
In both cases, the original actually appears after the child in the pokedex.

Additional group members
Some legendary Pokémon are extra members of a lesser legendary group. For several of them, enabling an encounter requires the player to have obtained its complete group. They can be superior, with a master-like role, a fourth hidden member, or even a weaker counterpart to members of a legendary group.

Event Fairies
Most generations introduced a standalone fairy-like event-Pokémon, with every base stats being 100. Note that Mew and Manaphy completely fit into this category, but are much more importantly additionally related to another pokemon each.

Standalone legendaries
Everyone except for 4 legendaries have been covered above. These 4 are similar to the ones in the minor Duos, powerful unique pokemon with interesting backstories/origins except they don't have a counterpart. They are hidden/extra legendaries towards the end of the dex (all event-pokemon or in the case of Heatran, not in a regional pokedex).
