Vidar's Mystical Boots are said to have rivaled his power, the Lightning God Thor. Thor is among the "10 Most Powerful Beings in the World". In addition, Vidar fought Issei using the Ragnarök Earth Berserk Armor. But after all, Issei won. That is why Issei and Vari are now candidates for their place in the "10 Most Powerful Beings of the World". And I think that this will be confirmed by Issei's victory over Indra.
