For Ash, Pikachu is always a great choice as it's his most loyal and powerful partner. Alongside that, a strong flying type like Charizard could be useful. For Brock, his Onix would be a staple. And perhaps a water - type like Vaporeon could be good for him to balance his team. Since they are teaming up, having a psychic - type like Alakazam could also be beneficial as it can help in battles and also with communication in tricky situations.
Brock and Lucy could embark on a journey to find a legendary Pokemon. Brock's experience and knowledge of different Pokemon types would be useful, while Lucy's determination and unique battling style would complement him well.
One possible aspect of a Brock and Lucy fanfiction could be their adventures together. Maybe they team up to explore a new region in the Pokemon world, facing various challenges and making new Pokemon friends along the way.
